Embodiments of the present invention

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

Embodiments of the present application provide a data reading method, device, storage medium, and mobile terminal. Any of the data reading apparatuses provided in the embodiments of the present application may be integrated in a mobile terminal, and the mobile terminal may include terminal devices such as a smart phone, a Pad, a wearable device, and a robot. The mobile terminal includes a preset application program, and the preset application program can run in a startup mode (Direct Boot Mode) of the mobile terminal. Preferably, the mobile terminal is a mobile terminal installed with an Android system.

The corresponding data reading method, device, storage medium and mobile terminal will be described below respectively.

1a is a schematic flowchart of a data reading method provided by an embodiment of the present application, which is applied to a mobile terminal, and the data reading method includes steps 101 to 105, which may be specifically as follows:

101. Obtain private data of a preset application.

Preset applications refer to applications that can be run in the startup mode of the mobile terminal, such as some basic applications in the mobile terminal, including applications such as alarm clocks, emergency contacts, text messages, and phone calls. The private data includes the personal data related to the mobile terminal user, such as contact information, communication friend information, and communication information communicated with the communication friend stored on the mobile terminal.

Taking the preset application as the emergency contact application as an example, the emergency contact application adds one or more contacts in the contact database (the database used for storing contact information in the mobile terminal, commonly known as the phone book) as Emergency contacts, and provide relevant entrances when the screen is locked, so that mobile terminal users can quickly call emergency contacts. In this way, the privacy data includes emergency contact information that can be contacted in an emergency, the emergency contact information is consistent with the corresponding contact information in the contact database, and specifically includes the contact name, contact phone number, contact email, contact information One or more information such as person unit, contact picture, contact QR code, etc.

Taking the preset application as the phone application as an example, the privacy data corresponding to the phone application includes the contact information in the contact database, and each contact information specifically includes the name of the contact, the phone number of the contact in the corresponding contact database One or more of the information, such as number, contact email, contact unit, contact picture, contact QR code, etc. The privacy data corresponding to the phone application also includes information such as call records.

The private data of the preset application can be obtained in various ways. Before describing how to obtain the private data of the preset application, first describe the startup mode and normal mode of the mobile terminal, and the area where the mobile terminal stores data.

Boot mode, Direct Boot Mode, also called direct boot mode, refers to a new mode entered after the mobile terminal is started, until the mobile terminal user unlocks the mobile terminal and the mode ends.

The normal mode, also called the non-direct boot mode or the non-direct boot mode, refers to the mode corresponding to the stage after the mobile terminal user unlocks the mobile terminal.

In order to support the startup mode, the mobile terminal provides two areas for storing data in advance:

1) Credential encrypted storage, also referred to as CE storage area, the storage area where the mobile terminal stores data by default, and can also be understood as the default storage location, which can only be used after the mobile terminal user unlocks the mobile terminal. Storage space, which is available in normal mode. As shown in Figure 1b, the preset application can normally read and write data stored in the credential encrypted storage area (the default storage location) in normal mode.

2) Device encrypted storage, also referred to as DE storage, mainly corresponds to the storage area used in startup mode, but the storage space of this storage area can be used in both startup mode and normal mode .

In general, the data that the default application needs to use in startup mode can be stored in the device's encrypted storage area. However, for private data, such as contact information in the contact database, call records, communication friend information, communication information with communication friends, etc., in order to protect user privacy, it is not suitable for excessive exposure without unlocking. Therefore, the private data of the preset application is placed in the storage area where the data is stored by default, that is, the credential encryption storage area. In boot mode, the data of the credential encrypted store cannot be read. As shown in Figure 1b, the default application cannot normally read and write data stored in the credential encrypted storage area (the default storage location) in boot mode.

Therefore, step 101 includes: obtaining the privacy data of the preset application program from the credential encryption storage area in the normal mode of the mobile terminal; or

If the data addition instruction of the preset application program is received, the privacy data to be added by the preset application program is acquired according to the data addition instruction.

Wherein, the privacy data of the preset application is obtained from the credential encryption storage area in the normal mode of the mobile terminal. For example, if the preset application is an emergency contact application, the private data of the emergency contact application, that is, the corresponding emergency contact information, is obtained from the credential encryption storage area in the normal mode of the mobile terminal; For the phone application, the private data of the phone application, that is, all the corresponding contact information, is obtained from the credential encryption storage area in the normal mode of the mobile terminal.

Wherein, if the data addition instruction of the preset application program is received, the data addition instruction carries the privacy data to be added by the preset application program, and the privacy data to be added by the preset application program is obtained according to the data addition instruction. For example, if the default application is a phone application, the data addition instruction of the phone application carries the privacy data to be added, such as the contact information to be added or the call record information to be added, the data addition instruction is used It is used to store the carried contact information to be added in the contact database, or to store the call record information to be added. In this way, if a data addition instruction of the phone application program is received, the contact information to be added or the call record information to be added of the phone application program is acquired according to the data addition instruction. The data addition instruction of the contact information to be added can be triggered by the save control on the new interface corresponding to the contact database, that is, trigger the save control on the new interface corresponding to the contact database to trigger the data addition instruction. The data addition instruction of the call record information to be added may be generated when an outgoing call or an incoming call is detected.

In some cases, step 101 includes: obtaining the privacy data of the preset application and the privacy data identifier corresponding to the privacy data from the credential encryption storage area in the normal mode of the mobile terminal; or

If the data addition instruction of the preset application program is received, the privacy data newly added by the preset application program and the privacy data identifier corresponding to the privacy data are obtained according to the data addition instruction.

Understandably, the privacy data includes a corresponding privacy data identifier, and the privacy data identifier can uniquely identify the privacy data. If the private data is contact information, the private data identifier corresponds to the identification information of each contact. Specifically, the external Uniform Resource Identifier (URI) of the contact can be used as the privacy data identifier, the identifier (storage number, etc.) corresponding to the contact information stored in the contact database can also be used as the privacy data identifier, or the Contact phone numbers as privacy data identifiers, etc.

Obtain the private data identifier, so as to quickly and conveniently find the private data corresponding to the private data identifier through the private data identifier, and improve the user experience.

It should be noted that the emergency contact application program and the phone application program mentioned in the embodiments of this application are only examples of preset application programs, so as to facilitate the understanding of the content in the embodiments of this application, they do not constitute a preset application program. Program limitations.

102. Back up the private data to the device encrypted storage area in the startup mode of the mobile terminal.

After acquiring the private data of the preset application, back up the private data to the device encrypted storage area in the startup mode of the mobile terminal. Understandably, since the data in the device encrypted storage area in the startup mode of the mobile terminal can be used in both the startup mode and the normal mode, in one case, the acquired preset application The private data is only stored in the encrypted storage area of the device in the startup mode, thus reducing the occupied storage space of the mobile terminal. Correspondingly, when obtaining private data, it is obtained from the encrypted storage area of the device.

Preferably, the privacy data of the preset application is stored not only in the device encrypted storage area in the startup mode, but also in the credential encrypted storage area in the normal mode, so that it is convenient for other applications to use the credential encrypted storage area in the normal mode to store in the encrypted storage area. privacy data and improve usability. Understandably, on the basis of storing private data in the credential encrypted storage area in normal mode, the corresponding private data is obtained and backed up to the encrypted storage area of the device. The bad influence caused by the inability to obtain the private data in the credential encryption storage area in the normal mode in the normal mode improves the user experience. Specifically, as shown in FIG. 1c , the privacy data of the preset application is stored in both the credential encrypted storage area in the normal mode and the device encrypted storage area in the startup mode. In normal mode, preference is given to private data stored in the credential encrypted store (the default storage location). In boot mode, private data stored in the device's encrypted storage is used in the form of single-app dual data storage.

The private data can be backed up to the device encryption storage area in the startup mode of the mobile terminal, and stored in the form of key-value pairs. If the amount of private data is relatively small, SharedPreference can be used to store it. Correspondingly, the private data will be automatically stored in the encrypted storage area of the device. Among them, SharedPreference, referred to as SP, is a storage method provided by the Android system to store some simple configuration information. Specifically, the Map data structure is used to store data, which is stored in the form of key-value pairs, and the data is stored in the mobile terminal in XML format, and the corresponding storage file is stored in /data/data/ <package name>/shared_prefs directory. It is suitable for single process, small batch data storage and access.

In some cases, if the privacy data identifier is obtained in step 101, correspondingly, step 102 includes: backing up the privacy data and the corresponding privacy data identifier to the device encryption storage area in the startup mode of the mobile terminal.

103. When running the preset application program, detect whether the mobile terminal is in the startup mode.

When the mobile terminal runs the preset application program, it is detected whether the mobile terminal is in the startup mode. Wherein, whether the mobile terminal is in the startup mode can be detected by a preset function, and the preset function is UserManager. isUserUnlocked().

104. If the mobile terminal is in the normal mode, read privacy data from the credential encryption storage area in the normal mode. That is, if it is detected that the mobile terminal is in the normal mode, the private data is read from the storage area where the data is stored by default, that is, the credential encryption storage area.

105. If the mobile terminal is in the startup mode, read the private data from the encrypted storage area of the device in the startup mode. That is, if it is detected that the mobile terminal is currently in the startup mode, it can be understood that the mobile terminal is in the stage after startup but not unlocked, and correspondingly, the private data is read from the encrypted storage area of the device.

It should be noted that steps 103 to 105 may be understood as corresponding to the steps related to querying private data.

In the above embodiment, the private data of the preset application is extracted and backed up to the storage space of the device encrypted storage area in the boot mode, so that the private data can be read from the device encrypted storage area in the direct boot mode. In this way, the preset application program can run normally in the direct startup mode, so as to solve the problems that the application cannot be used in the direct startup mode, or have abnormal usage or defects, and improve the user experience.

2 is another schematic flowchart of the data reading method provided by the embodiment of the present application, which is applied to a mobile terminal. The data reading method includes steps 201 to 206, which may be specifically as follows:

201: Obtain privacy data to be used by a preset application in the startup mode of the mobile terminal and a privacy data identifier corresponding to the privacy data.

Taking the default application as the emergency contact application as an example, the private data that the emergency contact application needs to use in the startup mode of the mobile terminal includes the contact phone number. Emergency contact application to dial the phone number, quickly call emergency contacts, and realize emergency calling function. The private data to be used by the emergency contact application in the startup mode of the mobile terminal may further include the contact name, so that when the emergency contact is called, the contact name is displayed at the same time, so as to improve the user experience. Correspondingly, the privacy data identifier of the emergency contact application refers to the identification information of each emergency contact. It can be understood that the emergency contact information includes multiple different pieces of information, and the multiple different pieces of information are not necessarily required to be used in the startup mode. Therefore, only private data to be used by the emergency contact application in the startup mode is obtained.

Taking the preset application as the phone application as an example, the privacy data that the phone application needs to use in the startup mode of the mobile terminal includes the contact phone number. Understandably, with the contact phone number, it is possible to communicate with the contact. Telephone communication, realize the corresponding voice communication function. The privacy data to be used by the phone application in the startup mode of the mobile terminal may also include the contact name, so that when the phone communicates with the contact, the contact name is displayed at the same time, and the corresponding contact name and the corresponding contact name are displayed in the call record. Contact phone number to improve user experience. Correspondingly, the privacy data identification of the phone application refers to identification information of each contact. Likewise, it is understandable that only the private data that the phone application needs to use in the startup mode is obtained.

It can be understood that the privacy data to be used by the preset application in step 201 in the startup mode of the mobile terminal, compared with the privacy data of the preset application in step 101, the privacy data to be used in the startup mode is different. The corresponding set is less than or equal to the set corresponding to the privacy data of the preset application.

Specifically, step 201 includes: obtaining private data to be used by a preset application in the startup mode of the mobile terminal from the credential encryption storage area in the normal mode of the mobile terminal; or

If the data addition instruction of the preset application program is received, according to the data addition instruction, the privacy data to be added by the preset application program and to be used in the startup mode of the mobile terminal is obtained.

Specifically, please refer to the corresponding step description above, which is not repeated here.

202 , back up the privacy data and the privacy data identifier to the device encrypted storage area in the startup mode.

Correspondingly, the private data that the preset application program needs to use in the startup mode of the mobile terminal obtained from the credential encryption storage area in the normal mode of the mobile terminal is backed up to the device encryption storage area in the startup mode. Or back up the privacy data to be used in the startup mode of the mobile terminal to be added to the preset application to the encrypted storage area of the device in the startup mode. In this case, the privacy data to be added needs to be saved. to the default storage location, which is the credential encrypted storage area.

Since the set of privacy data to be used by the preset application obtained in step 201 in the startup mode of the mobile terminal is less than or equal to the set of privacy data of the preset application in step 101, the set of privacy data to be used in the startup mode is After the private data is backed up to the encrypted storage area of the device, the private data that the preset application needs to use in the startup mode can be obtained when the preset application is running, which ensures the normal operation of the preset application; at the same time, it can maximize the It protects the privacy of user data and minimizes the exposure of private data; it also reduces the consumption of unnecessary storage space and reduces the storage space for mobile terminals to store private data. In addition, the privacy data identification is also backed up, so that the corresponding privacy data can be queried more conveniently and quickly according to the privacy data identification, and it is convenient to synchronize the privacy data corresponding to the privacy data identification in the encrypted storage area of the certificate and the encrypted storage area of the device. Such as synchronous update and so on.

203. When running the preset application program, detect whether the mobile terminal is in the startup mode.

204. If the mobile terminal is in the normal mode, read the privacy data from the credential encryption storage area in the normal mode according to the privacy data identifier.

Corresponding private data can be quickly read from the credential encrypted storage area according to the private data identifier.

205. If the mobile terminal is in the startup mode, read the privacy data from the device encryption storage area in the startup mode according to the privacy data identifier, and monitor the broadcast message of the mode switching, which is to switch from the startup mode to the normal mode.

Corresponding private data can be quickly read from the encrypted storage area of the device according to the private data identifier.

It should be noted that if the mobile terminal is in the startup mode, it means that the mobile terminal is in the stage after startup but before unlocking. However, the user unlocking is an irregular behavior. When it is detected that the user unlocking is successful, it will enter the normal mode. In this way, in some cases, it will involve the situation of reading private data when the two modes are switched between modes. Since the startup mode is the mode corresponding to the stage after the mobile terminal is started but not unlocked, there is only one case of mode switching, that is, when the mobile terminal is successfully unlocked, the startup mode of the mobile terminal is switched to the normal mode.

It is assumed that the user of the mobile terminal opens the preset application in the startup mode, and the preset application reads private data from the device encrypted storage area. After the mobile terminal user successfully unlocks the mobile terminal, the mobile terminal has entered the normal mode. If no mode switching is detected, the mobile terminal still reads the private data in the startup mode, which may lead to a bad user experience. So in the process of mode switching, how to deal with it?

The broadcast message of the monitoring mode switch, the broadcast message is "android.intent.action.USER_ UNLOCKED", this broadcast message can monitor the mode switching of the mobile terminal user from the startup mode of the mobile terminal to the normal mode.

206 , if the mode switching broadcast message is monitored, re-read the privacy data from the credential encryption storage area in the normal mode according to the privacy data identifier.

If the broadcast message of mode switching is monitored, the private data is read from the credential encryption storage area again according to the private data identifier to complete the switching of private data reading and improve the user experience. If the broadcast message of the mode switch is not monitored, the monitoring will continue.

For steps not described in this embodiment, please refer to the corresponding description above, and details are not repeated here. This embodiment further defines that the acquired privacy data is the privacy data that the preset application program needs to use in the startup mode; and further defines the processing of special cases, that is, when two modes are involved in the mode switching, the privacy data is read. handling of the situation.

In some cases, it also involves modifying the private data of the credential encrypted storage area in the normal mode. At this time, it involves the private data of the credential encrypted storage area in the normal mode and the device encrypted storage area in the boot mode. Synchronization of private data. Specifically, please refer to FIG. 3 , which is another schematic flowchart of a data reading method provided by an embodiment of the present application. The data reading method includes the following steps:

301. If a data operation instruction in the credential encryption storage area of the mobile terminal is received, determine the operation type, the data to be operated, and the data identifier corresponding to the data to be operated according to the data operation instruction.

Understandably, the data operation instruction carries information such as the operation type, the data to be operated, and the data identifier corresponding to the data to be operated, and the operation type, the data to be operated, and the data identifier corresponding to the data to be operated are determined according to the data operation instruction. The data operation instructions include data update instructions and data deletion instructions, etc., and further include privacy data update instructions and privacy data deletion instructions, and the corresponding operation types include privacy data update and privacy data deletion. The data to be operated, correspondingly, includes the data to be updated and the data to be deleted. For example, for emergency contact applications and phone applications, the data to be operated involves contact information, that is, the data to be operated includes contact information; the operation of the contact information, specifically, the contact information in the contact database Person information to operate; correspondingly, the data identification corresponding to the data to be operated is the identification information of the contact to be operated. Of course, for a phone application, the corresponding data to be operated also includes call records and the like.

Understandably, because the private data may be backed up from the credential encrypted storage area in the normal mode to the device encrypted storage area in the boot mode, and the set of private data in the credential encrypted storage area is greater than or equal to the privacy of the device encrypted storage area. A collection of data, so, in general, synchronization is required when operating on private data in a credential encrypted store.

302. Detect whether the data identifier includes a privacy data identifier.

Since the data to be operated may not involve the private data saved in the encrypted storage area of the device, it is necessary to detect whether the data identifier to be operated includes the private data identifier. For example, for the emergency contact application, when the contact information in the contact database in the credential encrypted storage area needs to be operated, the data to be operated may not be the emergency contact involved in the emergency contact application.

If the data identifier does not include the privacy data identifier, directly perform an operation matching the operation type on the data to be operated in the credential encryption storage area according to the prior art; if the privacy data identifier is included, go to step 303; The technology performs an operation matching the operation type on the data to be operated in the credential encrypted storage area.

303. Acquire corresponding privacy data in the encrypted storage area of the device according to the privacy data identifier.

Since the private data identifier has a corresponding association relationship with the private data, the corresponding private data in the encrypted storage area of the device can be obtained through the private data identifier.

304. Perform operations on the private data in the encrypted storage area of the device according to the operation type and the data to be operated.

If the operation type is an update operation, update the private data in the encrypted storage area of the device according to the data to be updated; if the operation type is delete, delete the private data in the encrypted storage area of the device according to the data to be deleted.
